2013-11-12Move some system services to their own sub package.Amith Yamasani
As a next step they can be moved into separate directories to be built as separate modules that may or may not be included in a particular configuration. Moves AppWidgetService, BackupManagerService, ClipboardService, DevicePolicyMS, and WallpaperMS. Change-Id: I33e48d070f38186819d3a1d7a4dc3984b75a9eda
2013-07-16Refactoring of the print sub-system and API clean up.Svetoslav Ganov
1. Now a user state has ins own spooler since the spooler app is running per user. The user state registers an observer for the state of the spooler to get information needed to orchestrate unbinding from print serivces that have no work and eventually unbinding from the spooler when all no service has any work. 2. Abstracted a remote print service from the perspective of the system in a class that is transparently managing binding and unbinding to the remote instance. 3. Abstracted the remote print spooler to transparently manage binding and unbinding to the remote instance when there is work and when there is no work, respectively. 4. Cleaned up the print document adapter (ex-PrintAdapter) APIs to enable implementing the all callbacks on a thread of choice. If the document is really small, using the main thread makes sense. Now if an app that does not need the UI state to layout the printed content, it can schedule all the work for allocating resources, laying out, writing, and releasing resources on a dedicated thread. 5. Added info class for the printed document that is now propagated the the print services. A print service gets an instance of a new document class that encapsulates the document info and a method to access the document's data. 6. Added APIs for describing the type of a document to the new document info class. This allows a print service to do smarts based on the doc type. For now we have only photo and document types. 7. Renamed the systemReady method for system services that implement it with different semantics to systemRunning. Such methods assume the the service can run third-party code which is not the same as systemReady. 8. Cleaned up the print job configuration activity. 9. Sigh... code clean up here and there. Factoring out classes to improve readability. Change-Id: I637ba28412793166cbf519273fdf022241159a92
2013-05-02Start combining threads in system process.Dianne Hackborn
This introduces four generic thread that services can use in the system process: - Background: part of the framework for all processes, for work that is purely background (no timing constraint). - UI: for time-critical display of UI. - Foreground: normal foreground work. - IO: performing IO operations. I went through and moved services into these threads in the places I felt relatively comfortable about understanding what they are doing. There are still a bunch more we need to look at -- lots of networking stuff left, 3 or so different native daemon connectors which I didn't know how much would block, audio stuff, etc. Also updated Watchdog to be aware of and check these new threads, with a new API for other threads to also participate in this checking.

2013-02-20Add explicit userId to AppWidget binder callsJim Miller
Keyguard currently relies on being in the system process to grab the given user's widgets. When we split keyguard into a new process, it will need to have access to user-specific info to instantiate a specific user's widgets. In order to accomplish this, we add an explicit userid to each binder call as well as new permission check to allow keyguard access. This also fixes a potential race condition of having an incorrect user id due to an async call to change the user. Every binder call now has a specific user id. The user id is either the calling process user's id or an explicit one passed by applications like keyguard. It is created once when an AppWidgetManager is instantiated and remains for the lifetime of the object. Fixed bug where widgets sometimes didn't show up for secondary users. Moved permission check in AppWidgetService into getImplForUser() Refactored to use userid from context associated AppWidgetManager instance. Clean up AppWidgetHost to use userId from Context. Remove redundant userId check in checkPermission since it's handled by ActivityManager.handleIncomingUser() Removed redundant userid check. Upload after rebase...

2012-11-30Fix crosstalk between users for widgets hosted in lockscreenAmith Yamasani
This was initially about the Clock widget crashing repeatedly on some devices with multiple users. Turned out that there were race conditions when switching users that could result in remote views of one user calling back to the RemoteViewsAdapter in keyguard that in turn sent an incorrect widget id to a different user's widget, resulting in a crash. Since KeyguardHostView is instantiated in the same process for different users, it needs to carry a user identity to pass along to AppWidgetService so that remote views services were bound to the correct user and callbacks were attached and detached properly. Added some aidl calls that take the userId to do the binding properly. A more complete fix might be needed in the future so that all calls from Keyguard carry the user id. Also, there was a problem in comparing host uid for secondary users, since Settings for a secondary user has a different uid than keyguard. Not an issue on single-user systems. Changed the host.uid comparison to accomodate for the secondary user. Bug: 7450247 Change-Id: Idbc36e3c60023cac74174f6cb7f2b2130dd3052c

2012-08-31Remove Binder.getOrigCallingUid().Dianne Hackborn
Replaced all remaining places that used it with explicit user specification. While doing this, I ran into stuff that was creating PendingIntent objects (that now need to specify the explicit user they are for), which are also posting notifications... but have no way to specify the user for the notification. So the notification manager in the system process now also gets a formal concept of a user associated with the notification, which is passed in to all the necessary aidl calls. I also removed the old deprecated aidl interface for posting/cancelling notifications, since we now always need a user supplied. There is more work that needs to be done here, though. For example I think we need to be able to specify USER_ALL for a notification that should be shown to all users (such as low storage or low battery). Along with that, the PendingIntent creation needs to be tweaked to be able to handle USER_CURRENT by evaluating the user at the point the pending intent is sent. That's for another change, however.

2012-03-27User management and switchingAmith Yamasani
Broadcast intents that get sent out when users are added/removed/switched. More work on generating user-specific information in package manager queries. APIs to update user name and query a user by id. Removed Package.mSetStopped and mSetEnabled, since they're not user specific. User removal: - Cleanup ActivityManager, PackageManager, WallpaperManager, AppWidgetService and AccountManager. - Shutdown processes belonging to the user. Don't show vibrate option in long-press power if there's no vibrator. Lock the screen when switching users, to force unlocking. Change-Id: Ib23a721cb75285eef5fd6ba8c7272462764038fa
2012-03-22Package restrictions per userAmith Yamasani

Refactored pm.Settings and PackageSettingsBase to keep track of states per user. Migrated the stopped-packages.xml to users/<u>/package-restrictions.xml Changed intent resolution to handle individual user restrictions. Bunch of IPackageManager calls now have a userId argument.

2011-05-31Fix issue #4502672: Wrong xml resources used for homescreen widgets.Dianne Hackborn
There was a race in the system process between applying the initial configuration and executing code in higher-level system services like the app widget service that relies on the config. For some reason it starting showing up more after my code changes; it should now be completely fixed. Also fix the activity starting window to run in compatibility mode if its application is going to be in compatibility mode. And some various cleanup and small fixes.
